These transactions are conducted within the embedded secure element (eSE) chip of Samsung Electronics’ mobile devices, which holds one of the highest levels of security certification, CC EAL 6+.The Evaluation Assurance Level (EAL) is a numeric grading system that measures the security level of tech products and systems according to the Common Criteria (CC) security standard. It ranges from EAL0 to EAL7, with EAL7 representing the highest level of security.Leveraging this technology, the BOK and Samsung will continue their joint research to enhance security in offline payments using Samsung Galaxy smartphones and watches. Additionally, they aim to provide support for stable payments in situations where network connectivity is disrupted, such as during disasters.Growing interest in CBDCsGiven the global interest in CBDCs, with central banks worldwide exploring their potential, the research collaboration between the BOK and Samsung assumes great significance. The results of this partnership will guide further cooperative efforts to develop the international CBDC ecosystem.BOK Senior Deputy Governor Lee Seung-heon emphasized the significance of the joint achievement, expressing optimism that the partnership would keep Korea at the forefront of offline CBDC technology.Samsung’s Executive Vice President Choi Won-joon underscored that the company’s collaboration with the Korean central bank allowed Samsung to utilize its advanced security technology in digital currency.

British multinational banking conglomerate Standard Chartered has partnered with global crypto exchange OKX in Dubai on a collateral mirroring pilot program.Photo by appshunter.io on UnsplashOff-chain collateralIn a press release published on April 10, the companies set out details of the collaboration. The initiative will facilitate institutional clients to utilize digital assets and tokenized money market funds for trading as off-chain collateral. Trading activity requires the ongoing movement of funds and assets between custodians and exchange platforms. The activity is expensive and slow. Back in 2023, OKX had collaborated with crypto custodian Komainu and asset manager CoinShares to enable collateral mirroring to overcome this operational inefficiency. In that instance, CoinShares was enabled to trade on OKX using a collateral mirroring facility provided by OKX with Komainu acting as asset custodian. This latest initiative has also seen OKX work with alternative investment management firm Brevan Howard, global investment management company Franklin Templeton and local regulator in Dubai, the Virtual Assets Regulatory Authority (VARA).  Developed within regulatory frameworkThe collateral mirroring facility has been established on a pilot program basis to start with, having been developed within the regulatory framework established in Dubai by VARA. Standard Chartered will act as the digital asset custodian as part of the arrangement.  The press release points out that Standard Chartered is a Globally Systemically Important Bank (G-SIB), asserting that this will afford clients a higher level of security. By not having to manually move the digital assets, there is an additional security-related process improvement, given the ongoing risks associated with digital assets held on exchanges due to incidents of hacking. Hong Fang, OKX president, provided some insight into why the company has partnered with Standard Chartered, stating:”By leveraging Standard Chartered's position as a top custodian globally, as well as OKX's market leadership in cryptocurrency trading, the partnership sets an industry standard for current and potential institutional clients to deploy trading capital at scale in a trusted environment." OKX CEO Star Xu outlined on X that the service offering is geared towards tokenized money market funds with the aim of improving capital efficiency and counterparty risk protection. Standard Chartered launched its crypto custody services in Dubai last September. The service was established in partnership with Brevan Howard Digital, having been licensed by the Dubai Financial Services Authority (DFSA), the independent regulator for financial service providers located within the Dubai International Financial Centre (DIFC), an economic free zone. In October 2024, OKX selected Standard Chartered as its digital asset custodian for the crypto exchange platform’s institutional clients. First clientsBrevan Howard Digital and Franklin Templeton will participate as the first clients to trial the new service offering. Furthermore, as part of the collaboration, OKX platform users will gain access to tokenized on-chain assets developed and offered by Franklin Templeton. Franklin Templeton’s head of digital assets, Roger Bayston, commented on the firm’s on-chain product offering, stating: “By ensuring assets are minted on-chain, we enable true ownership, allowing them to move and settle at blockchain speed – eliminating the need for traditional infrastructure.”

Japanese Banking Giant Joins Tech Firms to Build Cross-Chain Stablecoin InfrastructureA major Japanese banking group has initiated a collaboration with technology companies to develop cross-chain infrastructure, according to a press release. The purpose of establishing a cross-chain system is to facilitate the trading of stablecoins across various public blockchains.Photo by Takashi Miyazaki on UnsplashThree companies team upIn this collaborative partnership, the Mitsubishi UFJ Financial Group (MUFG), the key developer of the stablecoin issuance management platform Progmat Coin, will join forces with Datachain, a cross-chain technology firm, and TOKI FZCO, which has global plans for providing cross-chain bridges. Together, they will work towards constructing infrastructure that enables cross-chain transactions involving stablecoins on different blockchain networks.Japan’s new regulatory boostWith the implementation of the revised Payment Services Act in Japan this year, companies completing the license registration process will gain the ability to issue and distribute various stablecoins on Progmat Coin. Furthermore, it is expected that stablecoins will be issued across different blockchains, including Ethereum.TOKI is currently in the process of developing a cross-chain bridge with the aim of introducing it this year. The cross-chain bridge developed by TOKI leverages blockchain intercommunication technologies such as the Inter-Blockchain Communication Protocol (IBC) or Datachain’s Light Client Proxy (LCP). These technologies ensure a high level of security and scalability for cross-chain transactions. Additionally, TOKI’s bridge boasts a highly efficient liquidity mechanism.The three companies strive to cooperate on this infrastructure project with an aim to launch it in the second quarter of next year.Government supportA couple of days ago, the Tokyo Metropolitan Government took a proactive step to support security token businesses based in Tokyo by offering subsidies. Given that both MUFG and Datachain are Tokyo-based companies, it appears that the Japanese government’s initiatives are beginning to yield positive results.
